microsoft network realtime inspection service puts cpu to 100%

Since today (I have installed Plex Media Server) I got my PC to peek at 100% cpu because of microsoft network realtime inspection service.
In Security Essentials (W7) there was the option in Defender to uncheck "Enable Network Inspection System".

I can not find this option in Win10. The only option I have is to disable the Realtime protection entirely.

Does anyone know how to turn of network inspection system or any other solution to this issue.

Regards,

Momoski

I run Windows 10 Enterprise Insider Preview Build 10074.

I also noticed this behavior after installing Plex (running Windows 10 Pro). Turning off "Cloud-based Protection" under Windows Defender Settings seemed to greatly reduce the high CPU cost.

Rather than disable cloud protection entirely I just excluded the Plex folder, Plex executables (including PlexScriptHost.exe), and my media folder from scanning by defender. You can find the settings near the on/off switches for defender.

The media folder might actually be a bit much but regardless that cut down the CPU cost tremendously. At the same time I'm not sacrificing much system security.
